From Glass Fiber to Coherent Transmission and Pluggable Optics: The Evolution and Future of Optical Networks

During the last decade, a new technology called coherent transmission made enormous scaling in optical network transmission possible. Combining the technology of digital signal processors (DSPs) with the application of phase modulation techniques (also common in mobile networks) to optical signals, coherent transmission technology enabled a further 100-fold increase in wavelength speed over what was possible with OOK technology since it was first introduced a decade ago.

The optical fiber that keeps data safe even after being twisted or bent

Physicists at the University of Bath in the UK have developed a new kind of fiber designed to enhance the robustness of networks. This robustness could prove to be especially important in the coming age of quantum networks. The team has fabricated optical fibers that can protect light using the mathematics of topology. Best of all, these modified fibers are easily scalable, meaning the structure of each fiber can be preserved over thousands of kilometers.

CI&M parent EBM unveils ‘Market Moves Infrastructure’ newsletter

Each week this month, CI&M parent company Endeavor Business Media (EBM) will be launching 5 new cross-market “Market Moves” newsletters, covering key industry sectors which transect the breadth of EBM’s publications.
As the first installment of the 5 new cross-market “Market Moves” newsletters, EBM has today officially launched its Market Moves Infrastructure newsletter.

Do Not Strip the Cladding When Stripping Fibers

When the Fiber Optic Association (FOA) began online certification testing, the results showed an unusual area of confusion. 25% of the test-takers missed the answer to what should have been a simple question: “What do you strip when you strip fiber for splicing or termination?” Instead of answering “the buffer coating,” a quarter of students answered that you strip the cladding. Even some instructors on their instructor certification exams answered that question incorrectly.

5 things you need to know about multifiber push-on connector testing –

NTT-Advanced Technology Research cites that 80% of network problems are due to dirty connectors, and the No. 1 cause of network failure is contaminated connectors. For MPOs, inspection and cleaning become even more critical. Given that a single dirty or damaged connector can impact 24 fibers—or more—with MPO connectors, taking critical communications lines out of service for troubleshooting will cause service interruptions for numerous customers.
How can the performance of MPO links be ensured? It all starts with testing. There are the five essential things you need to do: connector inspection, proper cleaning, polarity-type validation, continuity confirmation, and choosing the right referencing method.

Senko’s SN Uniboot connector takes home Platinum ‘Cabling Innovators’ honors

Senko Advanced Components, Inc. announced that its SN Uniboot connector was awarded Platinum Cabling Innovators honors, as presented by Cabling Installation & Maintenance at the at the recent BICSI Fall Conference 2022 (Sep. 25-29) in Las Vegas.
The SN Uniboot is a connector with a revolutionary design that allows four SN duplex connectors to be patched simultaneously in one operation. As noted by Senko, unlike 8-fiber MPO connectors comprising single polymer ferrules, the SN Uniboot’s design utilizes eight ceramic 1.25 mm ferrules that deliver carrier-grade performance and reliability.
Originally designed for use in multi-channel 400G data center transceivers within spine/leaf architectures, Senko reports that “the SN is proving to be much more than just a high data-rate equipment connection. The industry is fast discovering that when deployed as a backbone trunk solution, the SN Uniboot has significant benefits compared with existing legacy solutions,” adds a company statement.
